You can always fly a STAR according to an approach chart. Or, like what I did, I went on to an aircraft which had the STARS, copied down all the waypoint LAT/LON coordinates and added them on my CAPTAINSIM aircraft as waypoints. Once you add the grids, you can edit the particular altitude for each waypoint. When you review your route, it looks just as good as the regular STARS. That is how I fly the Kai Tak IGS 13 approach into Hong Kong for the time being until someone adds the STARS and SIDS  for Kai Tak.
